The Radiologists' Guide to Spinal Separation Surgery: What Does the Surgeon Want to Know?

Area of Science:

• Spinal oncology
• Surgical oncology
• Radiation oncology

Background:

• Spinal tumors cause significant morbidity and mortality.
• Separation surgery is an emerging technique in spinal oncology.
• This technique aims to decompress the spinal cord and facilitate radiotherapy.

Purpose of the Study:

• To present radiological experience with spinal oncology separation surgery.
• To report recommendations for preoperative and postoperative management.
• To evaluate the efficacy and safety of this technique.

Main Methods:

• Preoperative characterization of tumor volume and stability (e.g., ESCC grade, SINS).
• Clear communication of anatomical constraints for surgical approach and fixation.
• Systematic postoperative surveillance for recurrence and complications.

Main Results:

• Separation surgery facilitates high-dose stereotactic radiotherapy delivery.
• This approach achieves durable local control with minimized risk of radiation myelopathy.
• Radiological assessment is crucial for optimal surgical outcomes.

Conclusions:

• Spinal oncology separation surgery is a valuable technique for managing spinal tumors.
• Meticulous radiological evaluation and postoperative surveillance are essential for success.
• This approach holds potential for managing primary bone tumors of the spine.
